50 Ohm vs 75 Ohm Coaxial Cable: Start with the Equipment

SCHNAP lists RG58 and RG213 as nominal 50 ohm cable and RG59 as nominal 75 ohm cable. Impedance is a fundamental selection criterion: match the cable and connectors to the system design and equipment requirements. Also compare attenuation at the relevant operating frequency, conductor construction, bend radius, pulling limits and sheath suitability where those specifications are available.

Madison RG58 and RG213: 50 Ohm Cable

CC58100 RG58 is listed with a 20 AWG conductor of 19 tinned-copper strands, solid PE insulation, PVC sheath and nominal 4.95 mm outside diameter. CC213100 RG213 is listed with a heavier 13 AWG conductor of seven bare-copper strands, 2.5 mm solid PE insulation and PVC sheath. Both draft listings specify 50 +/- 3 ohms at 1 MHz and -15 to 70 degrees C operating temperature. The stated minimum installation bend radii are 50 mm for RG58 and 103 mm for RG213; RG213 also lists a maximum recommended pulling tension of 188 N. Check the exact reel SKU and frequency-dependent performance before selection.

Madison RG59: PVC and LSZH Options

CC59100 RG59 is listed as 75 +/- 3 ohms at 1 MHz, with a 23 AWG bare-copper conductor, 1.5 mm solid PE insulation, 6.2 mm nominal outside diameter and black PVC sheath. Its draft specifications include a 62 mm minimum bend radius, 107 N maximum recommended pulling tension and -15 to 70 degrees C operating range. CC59HF500 is a listed LSZH version with the same stated conductor and insulation dimensions, 6.2 mm nominal diameter and -25 to +90 degrees C operating range. An LSZH sheath does not by itself establish approval for every installation; verify the specified fire-performance requirements and product documentation.

MT1010B Telecommunications Wall Box

The MT1010B is listed as a UV-resistant, IP54 telecommunications wall box for external termination of Telstra residential lead-in cables. The draft says it is designed to comply with Telstra specifications and accommodates one 10-pair cable, ten 7 mm cables and two 7 mm earth cables. It closes with a captive Phillips/flat-blade screw. The source listing specifies installation by approved and qualified installers following Telstra installation practices. Verify the relevant network-owner requirements for the project.

Choosing Madison Products for a Communications Installation

Use a practical checklist: (1) system impedance and operating frequency, (2) conductor and cable dimensions, (3) sheath type and exposure conditions, (4) minimum bend radius and pulling limitations, (5) connector compatibility, and (6) required reel length. For external wall boxes, also confirm the mounting position, cable entries, environmental protection and authorised installer requirements.

Madison and Garland Cables

The source draft notes that Madison Technologies includes Garland Cables in its portfolio, while these products are shown under the Madison brand on SCHNAP. Use the SCHNAP listing and full SKU to identify the actual item; do not assume all Garland products are listed on the Madison brand page.

Madison — Frequently Asked Questions

What Madison products are listed by SCHNAP?

Selected RG58 and RG213 50 ohm cable, RG59 75 ohm cable in PVC and LSZH versions, and the MT1010B telecommunications wall box.

Is RG58 interchangeable with RG59?

No. The listed RG58 is 50 ohm and RG59 is 75 ohm. Select the impedance required by the connected equipment and system design.

What is the difference between RG58 and RG213?

Both are listed as 50 ohm cable, but RG213 has a heavier conductor and larger cable construction. Check bending, connector and frequency-dependent performance requirements.

What is the difference between PVC and LSZH RG59?

The draft identifies a PVC-sheathed CC59100 and LSZH-sheathed CC59HF500 with different stated temperature ranges. Confirm project fire-performance and installation requirements.

What is the MT1010B used for?

It is a listed UV-resistant IP54 external telecommunications wall box intended for specified lead-in termination applications; qualified installation requirements apply.

Does SCHNAP offer Madison bulk quotes?

Yes. Email [email protected] with the exact SKU, quantity and project details.

Can licensed electricians access protected pricing?

Eligible verified licensed electricians can apply for SCHNAP Trade Access. Protected prices are separate from public website prices.
